VERTICAL-SPACE REGISTER FOR TYPEWRITERS.

Application led April 2,

To all 'whom 2715 may concern Be it known that I, Lorn R. FULTON, acitizen of the United States, residing at Huntington Park, in the countyof Los Angeles and State of California, have invented new and usefulImprovements in Vertical-Space Registers for Typewriters, of which thefollowing is a specification.

My invention relates to vertical space registers for typewriters andconsists of the novel features herein shown, described and claimed.

An object is to provide a vertical spaceregister to be used inpredetermining the space to be covered by the typewriting work and meansfor indicating that the space has been covered.

Other objects and advantages will appear from the drawings andspecification.

The drawings illustrate the invention. h

Figure 1 is a fragmentary front elevation of `a typewriter provided witha vertical space register in accordance with the principles of myinvention, the parts being broken away and shown in section.

Fig. 2 is a fragmentary end elevation looking in the direction indicatedby the arrows 2 in Figs. 1 and 3.

Fig. 3 is an enlarged sectional detail on the line 3-3 of Fig. 2.

Fig. 4 is a sectional detail on t-he line 4-4 of- Fig. 3.

The details of the vertical space register `,for typewriters shown inthe drawings are as follows:

The typewriter `platen 1 is mounted upon a shaft 2, which may beoperated by a hand wheel 3. The shaft 2l extends through a frame bearing4 and the hand wheel -3 has a hub 5 fitting upon the end of the shaft 2outside of the bearing 4 and held removably in place by set screw 6.

In applying the vertical space register the screw 6 is loosened and thehand wheel 3 removed and a Spur gear 7 is rigidly mounted as by a key 8upon the shaft 2 against the bearing 4 and the hand wheel 3 may bereplaced. The bar 9 carrying the bearing 4 extends forwardly to make theregister supporting bar 10, and an attaching tension plate 11 fitsagainst the leftl hand side of the bar 9 and is secured in place byscrews 12 inserted through the plate and tapped into the bar. Theyhousin 13 is carried by the attaching plate 11 an has side plates 14 and1924. Serial No. 703,690.

15 above the supporting bar 10, a web 16 extending inwardly from thelower part of the plate 15, an extension side plate 17 extendingdownwardly from the web 16 and a second web 18 extending outwardly tothe plate 14.

A spur gear 19 is mounted against the extension plate 17 and turns upona screw 20 tapped into the plate 17 and the gear 19 meshes with the gear7. A third gear 21 fits against the inner face of the plate 14 and ismounted loosely upon a shaft 22 having an operating hand wheel 23 uponits outer end. The register or indicating wheel 24 is nonrotativelymounted upon the squared portion 25 of the shaft 22 between the gear 21and the plate 15 and a nut and washer 2G is mounted upon the inner endof the shaft 22 against the plate 15. A spring pressed pin 27 is mountedin a bore extending from the left hand face of the wheel 24 and bearsagainst the face of the gear 21 to make a frictional drive for theregister wheel 24 so that by manipulating the hand wheel 23 the register24 may be set as desired and then driven b friction from the platenshaft 2.

lndicating or register numbers 28 are formed upon the periphery of thewheel 24 and are visible one number at a time through -the opening 29 inthe web 16. The wheel 24 is o f such a size geripherally and the geartrain 21, 19 and is so proportioned that one revolution of the wheel 24will equal' eleven inches upon the sheet of paper 30 passing through thetypewriter and the numbers 28 reading from one to eleven around thewheel anti-clock wise when seen as in Fig. 2, each number on the wheelrepresenting an inch on the typewriter paper.

A bell post 31 extends to the right from the upper part of the plate 15,the post being rigidly screwed into the plate and the semispherical bell32 is mounted upon the post 31 and has a lug 33 extending inwardly fromits edge. A bell clapper 34 is adapted-to strike the lug 33 and has anarm 35 extending from the clapper 34 along side the plate 15 and tliebent at right angles and extending through the plate 15 to form apivotal Support 36 and then bent downwardly inside of the plate to formthe operating arm 37. A pin 38 projects from the right hand face ofthewheel 24 to engage the arm 37. The pin 38 is so located relative to thenumbers 28 that the time at which the bell will ring may be accuratelydetermined by used, the hand wheel 23 will bell mani ulating If it isdesired to work upon an 'ordinaryl sheet of paper thirteen inches long,the paper will be placed in position around the platen 1 so as to leavea margin of one inch at the top and then the hand wheel 23 manipulatedto bring the number eleven into position to be seen through the opening29. Then when the work proceeds until eleven inches, of aper have beencovered the number one wil appear through the opening 29 and the 32 willring to indicate that the work has reached to within an inch ofvtheloweredge of the paper and has covered a space of eleven inches. v

Where a. di'erent size of paper 1s being be operated to indicate tenornine or eight or any other desired number of inches to be covered by thetypewriting work, and as the work proceeds to the endthe bell 32 willring.

Thus, I have produced a device to be made either as a part of atypewr1ter or as an attachment to a typewriter, and which may be set topredeterminethe vertical space to be covered on a sheet of typewritingand to indicate visibly and .audibly when the space has been covered.

Various changes maybe made without departing from the spirit of myinvention as claime I claim:

1`. A space register for typewriters having a platen and a platen sha t,an indicating Wheel rigidly mounted on gear rotatably mounted on theindicating wheel shaft, a gear drive from said gear to the platen'shaft, and a frictional connection between the indicating wheel and thegear on the indicating Wheel shaft whereby the indicating wheel may beset independent of the rotation of the platen.

2. A space register for typewriters having a platen and a platen shaft,an indicating Wheel rigidly mounted on a shaft, a loose gear rotatablymounted on the indicating Wheel shaft. a gear drive from said gear tothe platen sha-ft, a frictional connection between the indicating wheeland the gear on the indicating wheel shaft whereby the indicating wheelmay be set independent of the rotation of' the platen whereby a visiblesignal is given, and means actuated b v the rotation of the indicatingwheel for giving an audible signal.

In testimony whereof I name to this specification.
